correlation,   etc   ; animal behavior; pigeons; probability;     Show all 4 Subjects
Abstract:
... When reinforcer availability on one alternative of a concurrent schedule is signaled by a discriminative stimulus, responding on that alternative decreases. We investigated how the correlation between signal presentation and reinforcement (signal reliability) affects choice between signaled and unsignaled alternatives. Six pigeons responded in a concurrent schedule, in which reinforcers on one alt ...

Abstract:
... Unlike the situation for humans and microbes, the active multiprotein assemblies of plants have not been systematically defined. A recent report by McWhite et al. remedies this by analyzing the protein complexes of 13 plant species, thereby defining core assemblies and providing an essential resource for interpreting the genotype–phenotype space of plants. ...

Abstract:
... Biological knowledge accumulated over the decades and advances in computational methods have facilitated the implementation of pan-genome analysis that aims at better understanding of genotype-phenotype associations of a specific group of organisms. Pan-genome analysis has been shown to be an effective approach to better understand a clade of pathogenic bacteria because it helps developing various ...

Abstract:
... Free-living microbes are generally capable of growing on multiple different nutrients. Some of those nutrients are used simultaneously, while others are used sequentially. The pattern of nutrient preferences and co-utilization defines the metabolic strategy of a microorganism. Metabolic strategies can substantially affect ecological interactions between species, but their evolution and distributio ...

Abstract:
... Pearson’s product moment correlation coefficient (more commonly Pearson’s r) tends to underestimate correlations that exist in the underlying population. This phenomenon is generally unappreciated in studies of ecology, although a range of corrections are suggested in the statistical literature. The use of Pearson’s r as the classical measure for correlation is widespread in ecology, where manipul ...

Abstract:
... Cow stayability plays a major role on the overall profitability of the beef cattle industry, as it is directly related to reproductive efficiency and cow's longevity. Stayability (STAY63) is usually defined as the ability of the cow to calve at least three times until 76 months of age. This is a late‐measured and lowly heritable trait, which consequently constrains genetic progress per time unit. ...

Abstract:
... Dispersal often covaries with other traits, and this covariation was shown to have a genetic basis. Here, we wanted to explore to what extent genetic constraints and correlational selection can explain patterns of covariation between dispersal and key life‐history traits—lifespan and reproduction. A prediction from the fitness‐associated dispersal hypothesis was that lower genetic quality is assoc ...

Abstract:
... Alternative reproductive tactics (ARTs) have improved our understanding of the evolution of adaptive variation; for instance, their study has led us to understand that the best phenotype (e.g. large and flashy) for a tactic that uses one mating behavior (e.g. court females) is often not the best phenotype (e.g. small and inconspicuous) for a tactic that uses a different mating behavior (e.g. chase ...

To determine the relationship between growth rate and wood density in plantation-grown aspen (Populus tremuloides Michx.), 199 trees in 20 clones were sampled from a 15-year-old clonal trial. This study found no evidence that fast-grown trees produce less dense wood. Phenotypic and genetic correlations between height, diameter, volume, and biomass ...
